[0029] The utility model provides the following description of reference drawings to help comprehensively understand various embodiments of the utility model as defined by the claims and its equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will realize that various changes and modifications can be made to various embodiments described herein without departing from the scope and spirit of the utility model.

[0030] In the description of the utility model, the orientation description such as the orientation or position relation indicated by up, down, front, back, left, right etc. based on the orientation or position relation shown in the drawings, is just for the convenience of describing the utility model and simplifying the description, and is not to indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore can not be understood as the limitation to the utility model.

[0031] It should be understood that when one element (for example, a first element) is "connected" with another element (for example, a second element), the element can be directly connected with another element, or there can be an intervening element (for example, a third element) between the element and another element.

[0032] The embodiment of the utility model provides a kind of press type key structure, such as Figures 1-3As shown, it comprises a plurality of pressing plates 100, a panel 200, a light guide device 300 and a switch box 400. The pressing plates 100 are used for the user to press, and each pressing plate 100 corresponds to a pressing key. The panel 200 is provided with a plurality of perforations 210 in an array, and the spacing between adjacent perforations 210 can be the same or different. The light guide device 300 can be used for light to pass through and can guide the light. The light guide device 300 is located below the panel 200, and the light guide device 300 comprises light guide plates 310 corresponding to the perforations 210 and elastically deformable, specifically, the positions and the number of the light guide plates 310 correspond to the positions and the number of the perforations 210 respectively, adjacent light guide plates 310 are independent of each other, and the top surface of the light guide plates 310 is provided with light guide portions 320. The pressing plates 100 are placed on the light guide plates 310, and the light guide portions 320 and the pressing plates 100 are located in the perforations 210. Each perforation 210 has a pressing plate 100 and a corresponding light guide portion 320. When the light guide portions 320 transmit light, the light can be emitted from the panel 200, thereby lighting the corresponding pressing key.

[0033] The switch box 400 is located below the light guide device 300, and the top of the switch box 400 is provided with a plurality of pressing pieces 410 corresponding to the light guide plates 310 and elastically deformable. The positions and the number of the pressing pieces 410 correspond to the positions and the number of the light guide plates 310 respectively, and the pressing pieces 410 are provided with through holes 420 for the light to pass through. The switch box 400 is provided with a plurality of groups of light emitting devices 510 corresponding to the pressing pieces 410 and a plurality of trigger devices 520 corresponding to the pressing pieces 410.

The light guide plates 310 abut against the pressing pieces 410, and the pressing pieces 410 abut against the trigger devices 520. Since the light guide plates 310 and the pressing pieces 410 are elastically deformable, when the user operates the pressing plates 100, the light guide plates 310 and the pressing pieces 410 are deformed correspondingly, thereby triggering the trigger devices 520, and the entire pressing key can respond to the pressing operation of the user. The trigger device 520 can be a press switch, a pressure-sensitive device or the like which can be triggered by the user's pressure.

[0034] When a certain trigger device 520 is triggered, the corresponding light emitting device 510 emits light, the light emitted by the light emitting device 510 is emitted from the through hole 420, then is emitted to the light guide plate 310 and is irradiated outwardly through the light guide portion 320, so as to indicate that the pressing key corresponding to the light guide portion 320 is triggered. Since adjacent light guide plates 310 are independent of each other, the light is difficult to pass through the light guide plates 310 to the adjacent light guide plates 310, and the adjacent pressing keys will not have the problem of light transmission, so the user will not make a mistake in operation due to the light transmission, thereby improving the user's experience.
